'SIGNALING DEVICE FOR AUTOMQBILES.

Specification. of Letters Patent. Palliad Apr.. 1913.

Application led Iarch 22, 1917. Serial N o. 156,518.

To au whom it may concern:

Be it known that I, Lorns THOMAS, a citizen or the United States, residing at Cleveland, in the countyT of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Signaling De vices for'Aut'omobiles, of Awhich the following is a specification. r Y

This invention relates to signals for automobiles, adapted to give notice to adjacent vehicles or persons of intended movements of the machine carrying the signals.

The device includes a stop signal which is operated by connection to the brake pedal, so that when the brake is applied a stop sign will be shown atithe rear.

Various other improvements will be apparent from the following description and the accompanying drawings.'

ln the drawings Figure 1 is side View of an auton'iobile provided with the device. Fig. 2 is a diagram of the wiring connections. Fig. 3 is a sectional view showing the contact pieces connected to the brake pedal.

Referring specieally to the drawings, *5 indicates a rear sign box and 7 the iront sign box, the latter being clamped to the filling neck 8 on the radiator.

The lamps in the left and-right compartments 12 and 13 are in circuits 16 and 1'? respectively with a battery 18, each circuit containing a switch 19 which may he of the push bnn jupe, convenientlyT mounted on a casing 20 attached to the steering wheel. It is intended that these lights shall he operated by' hand, by closing the appropriate switch and lighting the. corresponding lamp, to indicate an intended turn to the right or the left.

The lamp 15 in. the stop compartment 11 is in a circuit 21 with the battery, and with a pedal switch 22, and a. cut-out 'witch 23. The operation of the pedal si ch 22 is automatic with the movement of the brake 2d, and the details yare shown in On the toot board 25 of the car is mounted a tubular casing 26 the lower part of which incloses a fixed Contact piece 27 in Coperating with this contact piece is another contact 28 also in said circuit, and the latter Contact is carried at the lo-wer end of a plunger rod 29. coiled spring 80 is inclosed in the casino, e and presses against a collar on the plunger,

-and tendspo force the plunger down and close the contacts and thereby light the lamp 15 in the rear compartment 11. The upper end of the plunger 29 is connected to a link 5 32 which works loosely through a hole 33 in a bracket 34; fixed to the under side of the brake pedal 34 by a clip 35. The link rod 32 has a stop nut 36 on the upper end thereof.

, As well known the brake pedal is nor- Inally lifted by the brake spring` when the brakes are released, and the adjustment of are link 32 is such that when the pedal is lifted the plunger 29 is pulled up and the contacts 26 and 27 se arated. TWhen the pedal is pressed down in applying the brakes, the spring 30 pushes down the pluri# ger 29 and closes the contacts thereby light ing thelamp in the compartment 11 .and showing the step signal at the .fis the link 32 works loosely through hoc '33 further downward movement the pel is permitted. 'When the pedal is rel/ee: the plunger 29 is again pulled lamp circuit opened.

By the means described any intens`V f, change ot' movementof the vehicle can he exhibited to other adjacent vehicles, whe eby the danger of collisions is avoided, f ci S25 the apparatus may be applied to er1' L cars without material change of struct-11...,

claim:

ln a switch., the combination of a rel; brake pedal, abutting switch Contact spring pressed plunger carrying o switch contacts and tending to cl. switch, and liul; rod b., and the Ledal, said link rod having a 'sliding connection with the pedal ermittig relative movement between the plunger, to take up oi the pedal after the switch is closed.

Tn testimony whereof, I do stdin my nature in presence of two witnesses.
